Hello —,
I'm sorry for your problem,
I'm currently away from home, so I can't have a look a your problem, I come home in around 5 or 6 days, and then I'll look to your problem.
Thanks for your patience. By the way I had the same problem :
I had to read twice with my Xperia Sp while I only hate to read once with my note 4. Very weird.
I will investigate. Feel free to also contact me on other messaging apps.
